Specification of Letters Patent. Patented A111. 19119 Application filedAugust 3, 1918. Serial'No. 248,194. i

disposed transversely of the drain for com municating therewith.

provide on the plug of the clean-out pipe a member having a limitedguided movement relatively to the clean-out pipe, whereby to limit theopening movement of the plug and thereby, in preventing its completeWithdrawal, avoiding the misplacing or loss of the plug.

A further object of the invention is to dispose the plug when open in aposition to prevent the closing of the cover until the plug is restoredto the clean-out pipe, whereby the latter will not be thus accidentallyleft open for the escape of sewer gas.

Reference is to be had to the accompanying drawings forming a part ofthis specification, it being understood that the drawings are merelyillustrative of one example of the invention.

Figure 1 is a longitudinal. vertical section of a drain and trapequippedwith my invention, showing the c1ean-0ut plug open affordingaccess to the clean-out pipe and at the same time obstructing theclosing of the drain cover;

Fig. 2 is a simil. r view with the plug in position closing theclean-out pipe and with the drain cover in the closed position Fig. 3 isa partly sectional plan view.

The drain designated generally by the numeral 10 may be of any approvedform having a trap 11 leading to the soil pipe 12, the drain having aclean-out pipe 13 above the trap for affording access to the pipe 12,said parts being generally known. The numeral 14 indicates theperforated cover of the drain and will be hereinafter particularlyreferred to.

The clean-out plug 15 is adapted to be screwed into the end of theclean-out pipe 13 at the flaring mouth of the drain beneath the cover.In order to prevent the complete withdrawalof the plug the latterisequipped with a retainer 16, here shown as'U-shaped or of yoke form,the cross bar of which is SWlVGlGCl to the plug 15"by a bolt 17extending axially through said pl'ugQThus, the

plug may turn relatively to theretainer 16 in inserting and removing theplug. Said retainer has side arms 18 passing through fixed keepers 19on" theclean oiit pipe 13 at the interior, whereby as the plug isinserted or removed the arms 18 will have guided sllchng movement insaid keepers. The arrangement of the arms 18 and keepers 19 is v suchthat when the free ends of the arms are An important object of theinvention 15 to brought adjacent to the keepers the arms 'will engagethe keepers to prevent complete withdrawal of the plug 15 from thedrain, the arrangement in the given example consisting of a notch 20 ineach arm 18 whereby the arms will drop into engagement with the keepers.Thus, if it should be attempted to removethe plug through the top of thedrain after removing the cover 1 1, then the removal must be donedeliberately because the tendency of the arms 18 will be to engage theirnotched portions 20 with the keepers 19. The plug 15, however, with thearms 18 still engaging the keepers may be permitted to lie in theflaring portion of the drain as shown in Fig. 1, leaving ample clearancefor the insertion of a clean-out wire or other tool in the pipe 13.Thus, the accidental loss or displacement of the plug will be prevented.

I utilize the retainer plug to prevent the closing of the cover 14 byobstructing the closing movement thereof, for which purpose in theillustrated example a depending lug 21 is formed on or secured to thecover at the under side in a position to rest on the arms 18 or oneofthem, when the plug is in the open position as shown in Fig. 1. Thecover at the opposite end from the lug 21 has a lateral lug 22 engaginga mating notch 23 in the drain. Thus, the arrangement is such that theopening movement of the plug will carry the arms 18 in a path across thedrain and beneath the cover to form an obstruction to the latter.

I would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention, I do not limitmyself strictly to the mechanical details herein illustrated, sincemanifestly the same can be considerably varied without departure fromthe spirit of the invention as defined in the appended eiaiins.

Having thus describedmy invention,

claim as new, and desire to secure by Letters Patent:

1. A drain including a clean-out pipe extending laterally from thedrain, a cover for said drain, a plug for said pipe, and a member onsaid plug and movable therewith, in the-opening of the plug, in atransverse path below the cover to a position to ,obstrnctthe closing ofsaid cover until the plug is re- ,Pleeed i the ,Qleemeeb Pi e- 2 (traininfil lditlg a lateral elean-out m ne e the 0 said n ne, mean t l i th meiee i th nineteen t me said pipe t thee po it e the nlee in t a sevfreimsais rfimiei aed oac in m n 1 the cover and plug to cause the plugto ob struct the closing of the cover until the plug is in position inthe clean-out pipe.
